(Well, not "new" since that was 3 years ago, but you know what I mean.)

There are some minor modifications and updates - a Starfleet-arrowhead pattern on the tunics themselves, short sleeves as an option on some uniforms (Uhura's) besides McCoy's, etc - but the overall look is very similar, as was intended.

EDIT: Oh, and the cadet uniforms are much different, of course. Out with Finnegan's silver, in with reds.
